"All services are not necessary/not all services are necessary"- but which ones? I don't have small children, but I grant that others' children need to be educated. I don't have a car but I need city buses and taxicabs with streets and roads good enough to travel on; I don't ice skate but I am glad that people in this northern climate have a well maintained indoor rink that provides exercise and a place to learn skills while having a good time; I rarely use the city swimming pool but I'm glad others can; I need subsidized housing to be available for those whose income barely covers their monthly expenses; I need water and sewage services, electricity, phones, municipal offices, libraries, museums, concert halls, a city-owned ski area and lodge...

What don't I need? I need it all.
